Actually to join in the debate on salary briefly....
I fly for a rival 320 operator in the Phils, where the majority of Capts are ex-cebupac and they told me Cebupac has 'incremental' pay and a seniority list anyway.. so salary increases with every year of service. A couple of our Capts told me they had 10+ years service and when they left they were getting 300k PHP basic (before productivity)... so salary is not fixed from person to person.
As an aside i heard this was a sticking point when some senior Capts were offered the 330 as they were told they'd lose their seniority (as it was a new airframe) and would have to start from year 1 330 pay.
